i think you need to update bios via bios flashbback on the back of the motherboard. if your board shipped with an older bios then it wont have support for 14th series cpus. 

yeah sorry I forgot to add that part i tried that already still same error


Hello ZeroTwoFranx

Since you're still getting error code 00 after updating the bios, this makes me wonder if the bios update was successful.

To be sure you renamed the bios file and put it on your usb flash drive correctly, I made a quick video.





yeah thank you this is the way I did it the first time I followed the steps shown in this video and still get error code 00


To confirm the bios update was successful, when you press the bios flashback button, the led should start blinking. The blinking should get faster as it goes then stop when complete.  The update should take about 90 seconds.

Code 00 means the motherboard isn't detecting the cpu, but code 00 can be caused by other things too.

Some things that can cause code 00....

The 8-pin cpu power cable isn't installed, double check the connections at the psu and motherboard. If your psu has two of these cables, connect both 8-pin cpu power cables.

The cpu cooler is too tight, try loosening it a little. Make sure the cpu cooler fan is connected to the cpu fan header.

A short somewhere can cause code 00.

If you've swapped out your motherboard and cpu, we can probably rule these out. A dead cpu will cause code 00, a faulty motherboard can cause code 00.

Bent/Damaged cpu socket pins will cause code 00, remove the cooler and carefully inspect the cpu socket.
